LMR33620ARNXR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to minimize thermal impedance.
  • To ensure stability, use a minimum output capacitance of 10uF, and consider adding a 10nF-100nF ceramic capacitor in parallel with the output capacitor to filter high-frequency noise.
  • The maximum input voltage rating is 42V, but it's recommended to limit the input voltage to 36V to ensure reliable operation and minimize the risk of damage.
  • The LMR33620ARNXR is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
  • Use the formula: Pd = (Vin - Vout) x Iout + (Iq x Vin), where Pd is the power dissipation, Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
